Abigail Breslin, is that really you??
We barely recognized the grown-up "Little Miss Sunshine" star when she walked the TIFF 2013 red carpet on Monday for the "August: Osage County" premiere alongside co-star, Julia Roberts, who naturally stole some of the thunder away from the teen.
The 17-year-old sported a very mature look featuring a black floral print gown with a full skirt and a low-cut bustier which she paired with a cute (and age-appropriate) jean jacket and platform heels.
The "Ender's Game" star styled her peroxide blond hair into a messy-chic side ponytail and highlighted her pretty blue eyes with winged eyeliner and lots of mascara.
Breslin first came to the Toronto Film Festival as a spunky 14-year-old to support her film "Janie Jones" which included singing in front of a crowd at the Horseshoe Tavern.
Let's hope she surprises Toronto and breaks out into a song!
Abigail's in good company:
